    FYI: Use the paddle attachment for forming peaks. Otherwise with the whisk attachment, and it will be overmixed when you are almost done adding the butter, as it did with me.

    Also JaeMarie, the addition of the salt is due to the recipe using UNsalted butter - it is a way to control the amount of salt, because different brands use different amounts of salt in their butter. Buttercream made with half shortening will hold up better at room temperature, but the taste will not be the same. Powdered sugar is used to keep a nice consistency when not using egg whites, but a true buttercream is meringue-based (melted sugar with egg whites, whipped to stiff peaks)

    JaeMarie, Royal Icing does not contain butter, margarine or shortening. It is simply egg whites, confectioners' sugar, and water.

    Excuse me , but this is Royal icing...not buttercream. Buttercream is made with half shortening and half butter with confectioners sugar, and vanila. No salt.

    Would this buttercream be appropriate to decorate cut-out sugar cookies? My family is not a big fan of the hard, Royal Icing, though it makes them very pretty.

    looks like you need regular sugar to me.
